We share names of provinces with Belgium: Brabant and Limburg, but like I said, Belgium had its own ideas about becoming a country, so they were split up in a Dutch and Belgian part, back in the old days. In those, and some other, parts of Belgium they still speak Dutch.
And ironically, Belgium is quite split as I mentioned earlier (and has a ridiculous number of ministers). Some extremist parties would like to see the split official so that the Dutch part joins The Netherlands, the French part France, and the German part Germany. Or at least so that they're not in the same country anymore.
And just for the record, our national motto is: Unity makes strength. :lol:
